CARPET-Erie LOOPER.

SPECIFICATION forming p'art of Letters Patent No. 314,704; dated March31, 1885.

- Application filed January 522, 1884. (No model To all whom it mayconcern-.-

Be it known that I, HENRY ALEXANDER MORROW, a citizen of the UnitedStates, residing in the city and county of Philadelphia, and State ofPennsylvania, have invented a new and useful Carpet-Rag Looper, of whichthe following is a specification.

The object of my invention is to provide a cheap and simple device bywhich the ends of the ribbons or strips of stuff which are sub sequentlywoven or plaitcd into rag carpets or mats can be automatically united.

To the above end my invention consists in the apparatus hereinafterdescribed and claimed.

In the drawings, which represent a preferred construction of aconvenientembodiment of my invention, Figure 1 is a side elevation ofthe entire carpet-rag looper. (Shown applied to the edge of a .table orsimilar support.) Fig. 2 is an elevation of the said looper detaehedfrom the table. Figs. 3 and 4 are perspeetive detailed views showing thecarpetrag looper with its parts in two of the positions which theyoccupy during the forming of a knot between the adjacent ends of thetapes to be united. Figs. 5 and 6 are detailed views of the knot, theknot being shown in Fig. 5 before it is entirely tightened up, and inFig. 6 after it is entirely tightened up.

Similar letters of reference indicate corresponding parts.

In the drawings, A is an angular frame, best made substantially of theform represented in the drawings, which is adapted to be secured inplace upon the edge of a table, 13, or other bed by means of a thumbscrew, G. This removable frame contains the operative instrumentalitiesof my device, which are a fixed slitter, D, and a pivotedspringcontrolled slitter, E, which operates in connection with the fixedslitter. The fixed slitter is permanently erected in a socket, a, formedin that portion of the frame which is superimposed upon thesupporting-table, and consists, at its upper extremity, of aspear-headed blade supported upon and formed as a part of aslightlycontracted blunt-sided throat or shank, (Z. The pivoted slitteris similar in shape to the fixed slitter and pivoted within the samesocket, but is smaller and provided with a thumb-heel, e, or depressingplate, through the instrumentality of which it can be deflected awayfrom the fixed slitter, against which, under the stress of a spring, F,secured to the frame and abutting beneath said thumb-heel, it normallyrests at an incline, as represented in Fig. 1.

Such being a description of the devices composing my invention, itsoperation is as follows: In the normal position of parts the slittersoccupy the position represented in Figs. 1 and 2that is to say, theslitting-point of the pivoted slitter rests against the fixed slitterconveniently at some little distance below the extremity of said fixedslitter. In this position the ends of two tapes to be connected(designated in the drawings as t t are readily speared upon both of theslitters so as to rest upon the frame and surround the throat portionsof said slitters. After this has been done and the two extremities arein the position above described, pressure is brought to bear upon thethumb-heel of the pivoted slitter so as to tilt the latter away from thefixed slitter and into the position represented in Fig. 3, and, as soonas this in turn has been done, the opposite or free extremity of theunder tape is brought around and introduced between the slitters anddown into the cavity formed between the slitters in the socket of theframe, and then the pressure upon the thumb-heel is released and thepivoted slitter allowed to reassume its normal position against thefixed slitter, in doing which, however, the free or unslitted extremityof the under tape is firmly held between the slitters, and all that thenremains to be done in order to effect the knotting of the two slittedextremities of the tapes is to seize said two slitted extremities whichsurround the slitters and lift them together off the slitters in themanner represented in Fig. t. The above lifting off is attended with theknotting together of the under tape to form a slip-noose, (designated bythe letter a in Fig. 4,) within the noose of which the slit extremity ofthe upper tape is by its slit engaged, as will be readily understood bya reference to Fig. 4 and to Fig. 5 of the drawings. Tension exertedupon the free extremities of the tapes causes the slip-noose to knotupon the slit extremity of the neighboring tape and form a tightfastening or knot of the character represented in Fig. 6.

It will be readily understood that my device is of great value toweavers of rag carpet and mats, in which the knotting of the tapes,ribbons, or strips of material employed requires considerable time andoccasions the waste of a good deal of material.

The device is both cheap, simple, easy of operation, and not likely toget out of order.

It is obvious that the frame may be constructed as a stationary and notas a removable device, and that its form and mechanical construction mayvary, that represented be ing simply what I deem a good form. It is alsoobvious that the slitters can be applied in various ways, and that theirform may be varied, although that form in which both slitters have acontracted throat, about which the slitted extremities of the tapescling before being lifted off, is the best construction of which I nowhave knowledge.

The slliters are best made flat with respect to their facing sides, andtheir knife-edges are produced by the beveling off of the metal of theiroutside faces.

The office of the spring (represented and designated by the letter F) issimply to yieldingly retain the pivoted slitter against the fixedslitter, and the spring must therefore be of sufficient strength tomaintain the pivoted slitter against the fixed slitter with force enoughto retain against the friction of the lifted'ends the free extremity ofthe under tape when the latter has been introduced between the slittersand through the slits formed in the extremities of the tapes for thetime being surrounding the slitters. 5

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States 1. The combination ofa frame, afixed slitter, and a pivoted slitter, substantially as and 40 for thepurposes described. t

2. The combination of a retaining-frame, a fixed slitter, a pivotedslitter, and a spring for controlling the movement of the pivotedslitter, substantially as described.

. 3. The combination of the frame, the fixed sl tter having ablunt-sided throat. the pivoted slitter likewise having a blunt-sidedthroat, and provided with a thumb-heel or kindred projection, by meansof which it can be tilted,
